It can be also be stated that the ratio of the carbon to hydrogen to oxygen is 1: 2: 1 in the molecules of carbohydrates.

Explanation:
Genetic engineering or modification is a process whereby the genome of an organism is manipulated in order to achieve a desirable trait in the organism. In this question, a farmer uses an approved genetically engineered corn plant, which produces pollen that can make its own toxins to repel pests.
Using this genetically modified corn plant means that the farmer no longer require the application of chemical pesticide to control the pests affecting his corn plant. The impact on the farmer of growing such a variety of corn is that the financial costs for the farmer would be lowered since he won't have to purchase chemical pesticides any longer.
